DETAILED DESCRIPTION
The systems and methods described herein provide for a mobile device to receive a user input to initiate a communicative connection to an external device such as, for example, a display or audio output device. The mobile device is operative to determine a position of the external device relative to the position of the mobile device. The user may perform an input action such as, for example, a gesture or swipe on the mobile device screen in the direction of the external device that the user desires to use to present data or content from the mobile device. The system is operative to distinguish and recognize the relative position of multiple external devices in a given space.
In this regard, FIG. 1 illustrates a block diagram of an exemplary embodiment of a system 100 that includes a processor 102 that is communicatively connected to a memory 104, a display 106, an input device 108 and a network 110.
FIG. 2 illustrates an exemplary embodiment of a mobile device 200 that includes the system 100 (of FIG. 1). The mobile device 200 may include, for example, a smartphone, tablet, mobile personal computer, or any other suitable type of mobile device. The mobile device 200 includes a touchscreen display 204, and sensors 202. The touchscreen 204 is operative to receive touch inputs from a user which may include, for example, gestures using one or more fingers such as swiping gestures or scrolling gestures. A swiping gesture includes, for example, a user touching the touchscreen 204 with a finger and dragging their finger in a particular direction on the touchscreen 204 while maintaining contact between the finger of the user and the touch screen 204.
The sensors 202 may include any type of sensor that is operative to receive a signal from an external device. In one exemplary embodiment, the sensors 202 are operative to receive and sense inferred signals. In other embodiments, the sensors 202 may include audio sensing devices such as microphones. Alternatively, the sensors 202 may include antennas or other devices operative to receive signals from an external device.
The mobile device 200 may also include accelerometers (not shown) that may sense the motion of the mobile device 200. Such accelerometers may sense the motion of the mobile device 200 when the user makes a gesture with the mobile device 200 such as, for example, shaking the mobile device 200, or moving the mobile device towards an object such as, an external device or point in space.
FIG. 3 illustrates an exemplary embodiment of a system 300 that includes the mobile device 200, a first external device 302a and a second external device 302b. The external devices 302 may include any type of device or system that is operative to present content to a user, for example, a monitor, television, display, projector, audio system, audio/video system, or any combination of these systems. The external devices 302 include emitters 306a and 306b respectively that are operative to emit unique signals 304a and 304b. The emitters 306 may emit any type of suitable signal. In the illustrated exemplary embodiment 304, the emitters 306 are operative to emit an inferred signal. In alternate exemplary embodiments, the emitters, may emit for example, sound signals, light signals, or other types of electromagnetic signals.
In the illustrated embodiment, the sensors 202 of the mobile device 200 are operative to receive the signals 304a and 304b from the external devices 302a and 302b respectively and determine a direction from which the signals 304a and 304b originated from relative to the orientation of the mobile device 200. The mobile device 200 in the illustrated embodiment has more than one sensor 202, the mobile device 200 may use any suitable method for determining the direction from which the signals 304a and 304b originated from. In alternative embodiments, the mobile device 200 may only have a single sensor 202. The mobile device 200 may, for example, compare the strengths of the signals received from the external devices 302. Rotating the mobile device 200 changes the relative orientation of the sensors 200 to the emitters 306, and thus may be used to determine a relative direction of the external devices 302 to the orientation of the mobile device 200.
The signals 304 output from the external devices 302 may include data in any suitable format that may include for example, a unique identifier of the external device 302, a description of the external device such as, the type of device 302 (e.g., display, audio device, audio/video system), the operational specifications of the device 302 (e.g., display type, resolution, color, size), communication protocols or schemes supported by the device (e.g., wireless protocols), and any other data that facilitates a communicative connection between the mobile device 200 and the external devices 302.
FIG. 4 illustrates a block diagram of an exemplary method of operation of the system 300. In this regard, the system 300 may be arranged in an environment such as, for example a conference room. In the illustrated example, the first external device 302a is arranged on a first wall 401, and the second external device 302b is arranged on a second wall 403 that opposes the first wall 401. The mobile device 200 is arranged between the first wall 401 and the second wall 403.
In operation, the sensors 202 on the mobile device 200 receive signals from the emitters 306a and 306b. The mobile device 200 processes the received signals and determines a direction relative to the orientation of the mobile device 200 of the external device 302a and the external device 302b. In the illustrated example, the arrow 405 indicates the front of the mobile device 202 where the external device 302a is orientated to the left of the mobile device 202 and the external device 302b is orientated to the right of the mobile device 202.
The mobile device 200 receives the signals from the emitters 306 and may process the signals to identify specifications of each of the external devices 302. Once the mobile device 200 determines the relative orientation, direction, or position of the external devices 302, and other relevant information about the external devices 302 such as, the type of external device 302, and communication protocols or standards supported by each of the external devices 302, the user may perform an input action to identify which external device the user would like to use to present content that is sent from the mobile device 202 to the selected external device 302. In this regard, the input action of the user is a swipe gesture on the touchscreen 204 that is in the direction of the external device 302b. In the illustrated example, the arrow 402 illustrates the path of a finger of the user on the touch screen 204. Thus, the user may swipe or gesture towards the external device 302b when the user would like content sent from the mobile device 204 to the external device 302b. The content may include any type of data such as visual, graphical, video, audio, textual or other information that may be sent from the mobile device 204 to the external device 302b. Once the user makes the input action, a communicative connection 404 is initiated between the mobile device 200 and the second external device 302b. In the illustrated exemplary embodiment, the external device 302b includes a video screen and audio output such that once the communicative connection 404 is established between the mobile device 200 and the external device 302b, the mobile device 200 may send video and audio to the external device 302b for display on the screen of the external device 302b. Audio associated with the video may be output by the external device 302b or another system that is associated with the external device 302b. 
FIG. 5 further illustrates an example of the operation of an embodiment of the system 300. In this regard, the user has performed an input action such as a swipe in the direction of the arrow 502 on the touch screen 204 of the mobile device 200. The input action is in the direction of the first external device 302a. Once the mobile device 200 has received the user input action that is in the direction of the external device 302a, a communicative connection 504 is initiated between the external device 302a and the mobile device 200. As discussed above, the mobile device 200 may send any type of suitable content to the external device 306a for presentation to the user on the external device 302a. 
FIGS. 6A and 6B illustrate another example of operation of an exemplary embodiment of the system 300. Referring to FIG. 6A, after the mobile device 200 receives signals from the emitters 306a and 306b and determined a location of the external devices 302a and 302b relative to the orientation of the mobile device 200, the user performs an input action that includes accelerating the mobile device 200 substantially along the arrow 602 in the direction of the first external device 302a. Following the user input action that indicates that the user would like to display content on the first external device 302a, a communicative connection 504 is made between the mobile device 200 and the first external device 302a. Once the communicative connection 504 is established, content may be sent from the mobile device 200 to the first external device 302a and presented to the user on the external device 302a. 
FIG. 6B illustrates a subsequent user input action where the user has accelerated the mobile device 200 in a direction substantially along the arrow 604 in the direction of the second external device 302b. Following the user input action, a communicative connection 404 is established between the mobile device 200 and the second external device 302b. Following the establishment of the communicative connection 404, content may be sent from the mobile device 200 to the second external device 302b and presented to the user on the second external device 302b. The content sent to the second external device 302b may be the same or different content than the content sent to the first external device 302a. 
Although the illustrated exemplary embodiments described herein include one mobile device 200 and two external devices 302, alternate exemplary systems may include any number of mobile devices and external devices 302.
FIG. 7 illustrates a block diagram of an exemplary method of operation of an exemplary embodiment of the mobile device 200 (of FIG. 2). In block 702, the mobile device 200 receives a signal from the first external device 302a (of FIG. 3) and the second external device 302b. In block 704, the mobile device 200 processor determines the position of the first external device 302a relative to the orientation of the mobile device 200. In block 706, the mobile device 200 processor determines the position of the second external device 302b relative to the orientation of the mobile device 200. In block 708, the mobile device 200 receives an input action (e.g., swipe, or acceleration in the direction of the first external device 302a) that corresponds to the relative direction of the first external device 302a. A communicative connection is initiated and established between the mobile device 200 and the first external device 302a in block 710. In block 712, the mobile device 200 outputs data and content to the first external device 302a for presentation to the user on the first external device 302a. 
FIGS. 8A and 8B illustrate another exemplary method of operation of the system 300 (of FIG. 3). In this regard, referring to FIG. 8A, the external devices 302a and 302b are arranged on a wall 801. The proximity of the external devices 302a and 302b to each other may cause some ambiguity as to a direction that a user would direct an input action to choose which external device 302a or 302b to initiate a communicative connection with the mobile device 200. When the mobile device 200 determines that external devices 302a and 302b are in close proximity to each other, the mobile device 200 may display graphical or textual representations 802 and 804 on the screen 204 that represent the relative locations of the external devices 302a and 302b. 
Referring to FIG. 8B, the user has performed an input action in the direction of the arrow 806, which is towards the graphical representation 804 of the external device 302b. The input action initiates the establishment of a communicative connection 808 between the mobile device 200 and the external device 302b. Once the communicative connection 808 has been established, the mobile device 200 may send content to the external device 302b for presentation to the user on the external device 302b.
